"value": "A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable."

Un invitado virtual malicioso, en condiciones espec\u00edficas, puede desencadenar una escritura fuera de l\u00edmites en un bloque kmalloc-8 en un host virtual, lo que podr\u00eda conducir a una corrupci\u00f3n de la memoria del kernel y al p\u00e1nico del sistema. Debido a la naturaleza del error, no puede descartarse completamente el escalado de privilegios. Las versiones a partir de la v4.16 son vulnerables."
